Black spray in engine bay - factory?

i have this black spray. Itís hard, not like road tar. Itís been there as long as I can remember. It doesnít appear to be on anything but body of car, so it seems impossible that it came from the road. Is this from the factory? It not on car anywhere else except engine bay

Its from the wheel wells. Check the front and rear wheel wells. It was sprayed on from the factory.

Re: Black spray in engine bay - factory?

It'll come off. Hard part is removing it without removing the paint. The color under the car is mostly just overspray, no clear coat, so it comes off pretty easy if you scrub it.

Re: Black spray in engine bay - factory?

If you want it off, something that's worked for me is soaking it with trans fluid or parts washer solvent and gently wiping it.

Re: Black spray in engine bay - factory?

Thanks for your help guys. I'll probably leave it on there. My goal with the car is to keep as much from the factory as possible and/or period correct while keeping it driveable. Trying to make a time capsule out of this one. it would be a blast to pick up another Formula and make it a modern day street car, but I have another project waiting that will likely supersede that dream.

Re: Black spray in engine bay - factory?

Factory random sloppiness is hard to faithfully reproduce. With that said, I've had some luck removing stuff like that with a claybar.

The word "claybar" will be triggering jokes around here, forever!

Claybar is good, but not that good!

Re: Black spray in engine bay - factory?

There was a belt dressing back in the 90's that would also leave splatter like that inline with the belts-- but I think the under coating is what you see here.

Re: Black spray in engine bay - factory?

might try removing it with mineral spirits, it might cut it without removing paint. I would definitely check somewhere inconspicuous on a Q-tip before I tried it tho...

But again, anything you do will make a smeary mess, and then you have to clean that up too... I would leave it alone personally, unless you are planning on repainting the area anyway.
